5.4 Pulse Generator
The SP-20000-PMCL series has a frequency divider using the sensor clock as the basic clock and
four pulse generators. In each Pulse Generator, various Clear settings are connected to GPIO.
The following shows Pulse Generator default settings.
Table - 9 Pulse Generator default settings
5.4.1 Clock Pre-scaler
Clock pre-scaler (Divide Value) can set the dividing value of the frequency divider (12-bit
length) and the sensor clock is used for this. Four built-in pulse generators work by the
same clock. In the SP-20000-PMCL, the sensor pixel clock is 39.16 MHz.
5.4.2 Pulse Generator Selector
This is where you select one of the 4 pulse generators in order to set or modify its
parameters.

Note:]
When Pulse Generator Repeat Count is set to “0”, the camera is operating in free-running mode.
However, based on the above default settings, Length=1, Start Point=0 and End Point=1, Pulse Generator stops at High
output. Therefore, if Start Point =0 and End Point=1 are configured, Length should be

as the minimum active
